` PATENT OEEicE0 EDVIN JEWELL, OE GREENE, IOWA- BED-SPRING.

SPECIFICATION forming part of Letters Patent No.` 774,180, datedNovember 8, 1904.

Application led November 3, 1903. Serial No. 179,667. (No model.)

To all whom, it may concern:

Beit known that I, EDWIN JEWELL, a citizen of the United States,residing at Greene, in

the county of Butler and State of Iowa, have invented certain new anduseful Improvements in Bed-Springs; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to woven-wire bedsprings, and has for its object toprovide an improved supporting-frame therefor involving means forAadjusting the spring to take up the sag or slack thereofl to Acompensatefor stretching of the spring.

To the above ends the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claim.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Figure l is a plan view of the complete loedspring', some parts beingbroken away., Eig. 2 is a side elevation of the same. Fig.. 3 is asection on the line w3 of Eig. T1. Eig. 4 is a detail in side elevation,showing one end of the spring looking' at the opposite side from thatshown in Fig. 2; and Fig. 5 is an end elevation of the so-called.lock-lever.`

The supporting-frame of the springV is made up of side rails or bars 1and transverse tiebars 9., which parts are braced by diagonalcorner-strips 3. The members l and 2 are preferably formed ofchannel-iron. The ends of the side rails l are turned upward at 4. Atransverse spring-supporting rod 5, which is advisably in the form of atube or pipe, rigidly connects the upturned ends 4 of the side rails lat one end of the device, preferably at the head of the spring'. Awindlass-rod 6, which extends parallel with thevrod 5, is journaled inthe upturned ends 4 at the foot of the spring. This windlass-rod 6 isalso advisably in the .form of a pipe or tube, but is provided at itsprojecting ends with squared or angular Shanks 7 and 8.

The woven-wire spring' 9 is rigidly attached at one end to the fixed rod5 and at its other end to the windlass-rod 6. A lock-lever l0 has anangular perforation which fits on the squared or angular shank 8 of thewindlassrod 6. The free end of this lock-lever l0 is bent laterally andis provided with a notch 11, which engages with the upturned flange ofthe adjacent side rail 1 and holds the said lever against lateralmovement, and hence against displacement from the shank 8, as long asthe tension of the spring 9 is allowed to act thereon, this, ofcourse,being the normal action of the spring.

By means of a detachable hand-crank l2, having a socket which fitstheshank 7 of the windlass-rod 6, the said rod Vmay be turned so as tostretch the springk and take up any slack or sag therein due tostretching of the spring. This lever is indicated in the drawings, Figs.l .and 2, by dotted lines only. When the windlass-rod has been turned soas to take up the slack or increase the tension of the spring, thelock-lever 8 should be removed from the shank8 and replaced thereon inposition to hold the said rod in such new position. With the squareshank 8 it is evident that the lock-lever 10 may be set in any one offour different positions with respect to the rod, and hence that thesaid windlassrod may be locked in any one of four different positionswith respect to a complete rotation.

The device above described,while extremely simple and of small cost, isefcient for the purposes hadv in View. The importance of being able totake up the sag* of the bedspring' to compensate for stretching of thewoven Wire thereofiis too obvious to need further comment.

j By turning up the ends of the side rails l and by extending the spring9 over the upper portions of the rods 5 and 6 the woven-wire spring isthrown high above the rails and other frame portionspof the bed-spring.This is important, because it permits the spring to be sprung downwardto'a very considerable extent without engagement with the said frameportions. i

It will of course be understood that the device above described iscapable of modification within the scope of my invention as herein setforth and claimed.
